I have an Asus A8n5x and i've just fitted a Zalman ZM-NB47J passive heatsink to the board. Works like a charm Nortbridge temp is steady at 32 degree (idle) 34 degree (load). The cpu and gpu are also Zalman cooled I've got the massive CNPS7700-AlCu on my CPU and the VF900-Cu on my graphics card. As silent as a fan cooled board gets I gues.

I recently purchased the 939DUAL-VSTA by Asrock (the successor to the popular 939DUAL-SATA2). It's a socket 939 board with an expansion slot to add an AM2 processor and DDR2 memory, and includes a PCIe x16 *and* 8X AGP slot.

Requirements for "Quiet" Motherboards

- Stock passive chipset cooling. Check. I installed a Zalman 7700 AlCu and it clears the NB and RAM.

- Dynamic fan control for CPU and/or system fans either through the BIOS or software. Option for CPU fan control with a 4-pin fan header. Enabled/Disabled, If enabled you get the following 3 menu items:Target CPU Temp (C): 45-65Tolerance(C): 02 (does not seem to be adjustable)Target Fan Speed: Fast/Middle/SlowNo control for 3-pin fans. Has a 3-pin System fan header, I don't know if it's controllable or not yet.

- SpeedFan support if available for more control over fans in addition to BIOS control would be a welcome bonus. See above.

- CPU core under-volting option in the BIOS for reductions in power consumption and CPU temps. BIOS range from 0.8 to 1.45 V. My CPU is capped at 1.1 V. CnQ has an option in the BIOS, but I still haven't fiddled with much for quiet control.[/i]

**UPDATE**

I am now using Crystal CPUID to control multi/voltage and Speedfan for monitoring purposes. CnQ did work when I set Windows power management to Minimal, it downclocked to 1200 MHz (from 2600). Using Crystal, I have it set for the 3 settings of 5x/1.1V = 1 GHz, 10x/1.25V = 2 GHz, and 13x/1.375 = 2.6 GHz.

I guess that is the temp reported by the onboard motherboard sensor.
Problem is that sensor is generally not reporting the temp of the northbridge but rather the temp inside the case.
If you don't experience weird freezes or crash you are probably fine, but touching the heatsink with a finger should bring a nice surprise to you (a burning one).

Passive stock chipsetcooling
although the BIOS controll of fans only extends to the 4-pin CPUfan header (and can't controll 3-pin fans) Atleast one of the other three (and I suspect all three) of the 3-pin headers can be controlled via Speedfan
Allows undervolting with CrystalCPUID down to 0.8V, although BIOS is limitted to default voltages.

Hello, I would like to know if anybody on this forum is using MB Gigabyte 965 P - DQ6, as I intented to buy it for an Core 2 Duo E6300 CPU. I am very interested in silent computing, that is why I started to build my dream computer with an P180B Antec case.

any users opinion about Gigabyte 965 P - DQ6 mobo are welcome!!!

thnx

There seems to be a lack of info on which Core 2 Duo mobos support undervolting. I'd love to see more data on that. One thing I noticed is that most P965 mobos do not have fans on their chipsets and therefore are probably quiet out of the box. And checking the bios specs on the msi p965, it seems it only has overvolting, no undervolting. Very disappointing as I love to do overclocked undervolting.

This is one of the reasons that's holding me back from upgrading to Core 2. I'd like to know about Speedfan support and undervolting. I am wondering if there is a LGA775 motherboard similar to my DFI Ultra-D, which can drop all the way down to 0.900V and has 3 Speedfan-controllable headers.

I know that the Gigabyte GA-965P-DS3 and GA-965P-S3 allow undervolting down to the 0.5V range. I don't think they have fan headers controllable through Speedfan, though.

I can report on the ASUS P5B (non deluxe), which isn't too different from the P5B-E.

The NB is passively cooled, although the small heatsink gets finger burning hot even at stock speeds, so I have replaced it with a larger heatsink. The heatsink has hoop clips and no holes through the board making DIY custom heatsink replacements a bit tricky. The SB with heatsink, also gets pretty toasty, but that can be replaced fairly easily as there are holes through the board.

The board supports Speedfan to control the fans, but the board does not seem to be able to control 3 pin fans on the CPU header and there are no evident options in the BIOS to enable/disable 4-pin fan control.

I'm am running a Core 2 6300 cpu - lowest available voltage in BIOS is 1.225V but I am down to 1.16V using Rightmark CPU Clock util.

The BIOS's automatic fan speed adjustment can control the CPU & two chassis fan headers. Manual speedfan settings do a better job.

All the new Gigabyte P35 series have lower power motherboard components along with bios settings to drop cpu voltage down to .6v or so. Looks like possible winners from both reliability and silence standpoints.

Is there a list of Asus or other brand motherboards that support 3-pin CPU fan control?

Asus P5W DH Deluxe is one. Others?

The stock Intel cooler/fan has a 4-pin connector (no, not Molex; a 3-pin connector with an extra pin hanging off the side used for fan control). I'm guessing that almost every S775 board has at least a 3-pin connector and most have the 4-pin.

As far as controlling a 3-pin fan, most (all?) Asus motherboards have "Q-fan" in the BIOS, or you can turn that off and use Speedfan in Windows or pwm-config in Linux. I've recently bought an MSI AM2 board, a Biostar P965, and an EPoX 939, and all of those supported PWM on the CPU fan header.
